VASCULAR HOLE CLOSURE DEVICE
A device for closing an aperture in a vessel wall, the aperture having an external opening in an external region of the vessel wall and an internal opening in an internal region of the vessel wall. The device includes a covering member positionable inside the vessel against the internal opening of the aperture and having a dimension to prevent egress of fluid through the aperture. A securing member is positionable external of the vessel and has a plurality of pores extending therethrough. A flexible connecting member operatively connects the covering member and securing member and moves the securing member toward the covering member.
DEVICES, SYSTEMS, AND METHODS FOR ANCHORING SUTURES
Various devices, systems, and methods for anchoring sutures are provided In general, a suture anchor can include a groove formed in an exterior surface thereof and configured to seat a suture at least partially therein. The suture can be configured to automatically become seated in the groove during the advancement of the anchor into bone, such as by being rotated therein using a driver tool. The suture and the groove can have cooperating sizes such that the suture seated in the groove extends radially outward therefrom to be partially located outside of the anchor. This external portion of the suture can be press fit between the anchor and the bone, thereby securing both the anchor and the suture to the bone. This securing can occur as part of driving the anchor into bone.
Anchor apparatus
An anchor for anchoring tensile members to bone includes: a housing extending along a central axis, with a hollow interior; a collet in the hollow interior having a central bore for accepting tensile members and an exterior surface, the collet being configured to swage around and against tensile members; a sleeve having a peripheral wall defining interior and exterior surfaces, the sleeve disposed in the housing's hollow interior axially adjacent to the collet, and movable parallel to the central axis between first and second positions; and wherein at least one of the collet exterior surface and the sleeve interior surface is tapered and the sleeve and the collet are arranged so movement of the sleeve from the first position to the second position causes the sleeve interior surface to bear against the collet exterior surface, causing the collet to swage radially inwards around and against one or more tensile members.
Dual expansion anchor
A bone anchor, including: a bone engaging member including: a first proximal bone engaging portion and a second distal bone engaging portion; and an expansion feature configured to allow radial expansion of the first bone engaging portion and the second bone engaging portion; an expander having a first proximal expansion portion and a second distal expansion portion and displaceable between a first position relative to the bone engaging member and a second position relative to the bone engaging member; a tissue capture feature; and wherein the first expansion portion of the expander is configured to expand the first bone engaging portion of the bone engaging member and the second expansion portion of the expander is configured to expand the second bone engaging portion of the bone engaging member when the expander is in the second position.
DEVICES, SYSTEMS AND METHODS FOR TREATING BENIGN PROSTATIC HYPERPLASIA AND OTHER CONDITIONS
Extra-urethral implants and methods of use are disclosed. Implants can treat disorders or diseases of the prostate by, for example, enlarging the lumen of the prostatic urethra.
METHOD AND APPARATUS FOR MITRAL VALVE CHORD REPAIR
Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, the catheter can be anchored to a superior surface of a mitral valve leaflet and a leaflet anchor can be advanced into the mitral valve leaflet to secure the mitral valve leaflet to a leaflet suture. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.
Method and apparatus for meniscal repair
An inserter including a hollow elongated shaft extending along a central longitudinal axis and having a proximal end and a distal end with a lumen extending therethrough; a sharp point at the distal end of the hollow elongated shaft, the sharp point disposed eccentric to the longitudinal axis of the hollow elongated shaft; a handle at the proximal end of the hollow elongated shaft; and a drive shaft movably disposed within the lumen of the hollow elongated shaft.
MEDICAL SYSTEMS, DEVICES AND METHODS ADAPTED FOR TISSUE FIXATION AND APPROXIMATING TISSUE DEFECTS
A medical device for approximating and securing tissue without requiring knots includes a lock-head, a strap section, distal protuberance, and a leader section. The device also includes a transition section between the leader and the strap section and a stiffening section proximal to the protuberance. The leader section is used to draw the strap section into the body through small apertures in tissue and the transition section provides a gradual transition in stiffness and size between the leader and the strap section. Tensioner and cutter and a threading tool configured to be slidably removed from a lumen of the tensioner and cutter is provided. A blade within the lumen of the tensioner and cutter is provided to cut excess leader and/or strap when the procedure is completed.
Knotless suture anchor with unthreaded nose
A suture anchor has a tubular body having an axial bore therethrough with one or more purchase enhancements on an exterior surface of the body adapted to enhance purchase of the body within a bone hole. These are preferably screw threads. A distal nose of the suture body has a smooth exterior surface. A length of suture passes down along the exterior surface over the purchase enhancements, over the distal nose, and up into the bore. The smooth exterior surface of the distal nose allows tension of the suture to be held by the engagement of the nose within the bone hole thus making it easier to obtain proper tension as the remaining portion is engaged into the bone hole to provide final fixation.
Knotless suture anchoring using two awl shafts
Methods and systems are provided for securing tissue to bone. A surgical system can include a driver having a proximal handle and a driver shaft extending therefrom, a distal awl shaft, a proximal awl shaft separate from the distal awl shaft and movable with respect to the distal awl shaft, a suture anchor, and a dilator feature distal to the suture anchor. The distal and proximal awl shafts are receivable in at least part of a lumen of the driver. In a bone forming configuration of the system, in which the distal awl shaft is driven into bone, a distal end of the proximal awl shaft abuts a proximal end of the distal awl shaft. The proximal awl shaft can be moved proximally, such as by activating an awl handle coupled thereto, with respect to the distal awl shaft to move the system in a suture anchor insertion configuration.
